Question about LG 42PX5D 42 in. Plasma HDTV

1 Answer

I have a 42 " plasma LG. The picture went out but I still have sound. I opened the back and I have a 4A fuse blown on the Z Sus board. I disconected the ribbons and the connectors and I still have a short to ground on the load side of the fuse. Is there a good way to find what is wrong without having to replace the whole board?

LG 42PC!R Plasma TV turns on and then green led blinking with no ppicture and sound !


Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.

Capacitors are fine but no picture for rca tv


It could be a y-sus or z-sustain. There should be fuses located on both boards. Check the fuses for continuity.

There was a pop sound to the baCK OF THE TV AND NO


Y Sustainer problem. However, normally they have to change both Y Sus and Z Sus boards at the same time. If you lucky than it's just a fuse on the Y sustainer blown (the chance is very rare) otherwise the IPM (Intelligence Power Module) on the Y/X sustainer board is short. more then likely if you can get the IPM off of the board you will see that the components are shot, that is the popping noise you heard. shopjimmy.com has these boards some are cheap some are not...good luck

LG 42PX4MVH PLASMA TV - Sound but no picture.


You need the ysus board. This is a very common problem with LG's. If it is coming up with the fuse removed you are essentially removing the short from the power supply so that it can come up and deliver other voltages for sound and all. Check out encompassparts.com if you are going to try to repair this yourself. Thanks

My 5 year old plasma tv has sound but no picture what could this be?


No picture as in a black screen? or a picture with snow (noise)? If there is no picture at all (black screen) with no menu display when menu button is pressed, then it sounds like the y-sus and the z-sus boards are faulty..These are the boards located usually on the left and right edges of the screen. They are fused and these can blow, severing the supplt to the boards. These boards are used to deflect the electrical charge across the screen. If you have no picture then it sounds like both boards are down

One of the SUS panels will be defect.On these panels you will find several fuses,the panel with the broken fuse must be replaced.
Sus panels are the panels with the big cooling blocks.

No picture, sound ok


I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.

LG 42INCH PLASMA TV BLANK SCREEN


Open the back cover and check the fuses on Y Sus Board and X Sus Board. If you can find a blown fuse, just replace that board and your problem will be fixed.

42 inch LG Plasma TV - Lost picture


Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.
